Be it known that I, Gromme Cmsms, is" citizen of the French Republic, a? 48 Rue St. Lazaro, Paris, in the Reagan lieof France, have invented certain new and useful Improvements Fhlid-Compresm's, of which the ieHowing is s specification.-

It 13 mm! that in engines so fonstitned-ig is advantageous, in order to improve the meehnnicei eificiency, m [nouns-in saline-merit on the same tori the piston or, pistons of the engine and the, piston or pistons of n:- aisoheen suggnyd, Y W

compresmr. It has n "wnzh the same 030- ect in View, to make these pissons of considerable weight, with a view to eliminnting the purt piayed by the flywheel. But under these circumstances, the engine being vertical, the comparatively great Weight of the pistons acts as n resisting effort during their up stroke and a driving eiiort during their down stroke. This fact has the disadvantage that the work is not equal during the two strokes, which is prejudicial to the cficiency.

To remedy this, in accordance with the present invention the action of ihe ntrnospheric pressure on ihe compressor piston is utilized. The accompanying diagrammatic drawing, given by way of cxampie', will enable it: to he understood how this may he carried out. AB is the two-stage compressor cylinder, the upper side A constituting the first stage and the lower side B, the "chime ofwhich is diminished by a portion of reduced diameter serving as a guiding rt-ion of flue com pressor piston consiituting the second siege;
